What are the features of C++11 standard containers?

Can you explain the features of C++11 standard containers?

Sure! C++11 introduced several new standard containers like std::array, std::unordered_map, and std::unordered_set. These containers offer improved performance and new functionalities.

What are the advantages of using std::unordered_map?

The std::unordered_map provides average constant time complexity for insertions, deletions, and lookups, making it very efficient for large datasets.

How does std::vector differ from std::array?

std::vector is dynamic and can change size during runtime, while std::array has a fixed size determined at compile time.

Can you give an example of using std::list?

Certainly! std::list allows for efficient insertions and deletions from anywhere in the container. Here's a simple example: std::list<int> myList; myList.push_back(10); myList.push_front(5);
